§ 367.20 Depreciation accounting.
(a) Method. Service companies must use a method of depreciation that allocates in a systematic and rational manner the service value of depreciable property over the service life of the property.
(b) Service lives. Estimated useful service lives of depreciable property must be supported by objective evidence and analysis, including where appropriate engineering, economic, or other depreciation studies.
(c) Rate. Service companies must use percentage rates of depreciation that are based on a method of depreciation that allocates the service value of depreciable property over the service life of the property. Where composite depreciation rates are used, they must be based on the weighted average estimated useful service lives of the depreciable property comprising the composite group.
